NON-SKID TIRE-SHOE.

Specification of Letters Patent.

application filed February 15, 1913. Serial No. 748,544.

To all whom it may concern:

Be it known that l, HERMAN S'rnoiessox, a citizen of the United States,and a resident of the city of New York, borough of Manhatt-an, in thecounty and State of N ew York, have invented a new and lmproved Non-SkidTire-Shoe, of which the followingV is a full, clear, and exactdescription.

Among the principal objects which the present invention has in view are:to provide an article of the character mentioned having spaced-apartmembers movable relative the tire to form independent gripping sectionsarranged to permit the movement of the tire thereon; to provideresilient means for returning the gripping sections to their normalposition when permitted to do so; to provide means for adjusting theshoe to wheels and tires ,of diderent dimensions; to construct anarticle of the character mentioned in a manner to permit the removal forrepair or replacement, of sections thereof; to construct said articlewith econonly; and to provide an article of the character mentioned,which may be folded or packed within small compass.

One embodiment of the present invention is shown in the accompanyingdrawings, in which- Figure 1 is a side view of a fragment ot' a vehiclewheel having applied thereto a shoe constructed and arranged inaccordance with the present invention; Fig. 2 is an edge view oi a shoesection; Fig. 3 is a side view of an attaching plate having a mountingtherefor', F ig. 4 is a detail view in perspective, showing an endfragment ot' a guide rod and an adjusting connecting nut mountedthereon.

As seen in the accompanying drawings, the shoe is constructed of aseries of sections. The sections are duplicates, and each is providedwith a short guide rod 9, which is bent to a curve, the radius whereofis equal to the distance between the center of the hub and the rim ofthe average wheel. At each edge of the rod 9 is formed a screwthreadedsection 10. Mounted on the threaded sections 1() are nuts 11. One of thenuts 11, as shown in Fig. 4 of the drawings, is provided with anL-shaped arm 12, at the end whereof is formed an eyelet 13. At theopposite end of the rod 9, a nut 14 has an lL-shaped arm 15, at the endwhereof is formed a hook 16. The nuts 14 are turynished to provide forconnecting the various rods 9, to make a complete ring for the supportot the gripping sections. Permanently mounted in the eyelet 13 is aspiral spring connector 17. The connector 17 is shaped to form an endloop 18, which, when the rod is adjusted in service position, is engagedwith the hook 16. When the engagement is thus eilected, by manipulatingthe nuts 11 and 14, the rods are drawn toward each other, and a pullingstrain is imposed on each of the connectors 17. The springs forming theconnectors 17 are made from wire stider in action than that forming thebutter spring 19 with which each rod is provided. Between the nuts 11and 14 are mounted on each rod a hanger uplate 20 and a butter spring19. rlhe spring 19 operates to normally move the plate 20 upon which itbears, toward the opposite end of the rod 9, to rest against the nut 14.llVhen, however, a pulling strain is exerted upon the gripping section.with which the plates 2() are connected. the spring 19 yields to permitsaid plates to slide on the rods 9. The connectors 17, as above stated,have sufficient strength to hold the rods 9 in their initial positionuntil after the spring 19 has been collapsed. Thereafter, and prior tothe exertion of a breaking strain upon the structure, the springs 19yield to permit a separation of the rods 9, and to relieve the structurewhen a pulling strain is exert-ed upon the gripping sections. Each ofthe plates 20 is furnished with rivet holes 21, through which rivet-s 22are passed when mounting on said plates the Hexible grippers 23. Each ofthe grippers 23 consists of aI short length of flexible material, and isrigidly secured at both ends to a plate 20. The grippers 23 may beconstructed from any suitable material and may be provided with anysuitable engaging devices, such as rivets 24, shown in the drawings.

When the shoe is removed from the tire 25, the grippers 23 may bestraightened lengthwise and in this position be folded one upon theother, thus forming a condensed package. When the shoe is to beadjusted, this is easily accomplished by spreading the grippers over thetire and joining the loose or disconnected ends of any of the rods 9torque strain means for setting by means of the eyeleted arm 12 andthe'arm 15, the connector 17 being extended to engage the hooks 16.

. he operation of the shoe, when in servis as follows When each of thegrippers 23 engages the roadbed, it is permitted to slide on the rod 9against the spring 19 which is mounted on said rod. The independentaction of the gripper permits the necessary time for the end suctiondevices, such as lthe rivets 24: or the material of which the grippersare constructed, to eiectively engage the roadbed before the of thewheel is transferred t0 the .gripper. When the wheel rotates into theposition to lift the gripper from contact with the ground, the spring 19immediately moves said gripper to its initial position. In this manner,allowance is made for the inertia of the rotating wheel during theperiod of skidding, while providing in engagement the griplice position,

pers of the shoe.

Having thus described my invention, I claim as. new and desire to secureby Letters Patent A tire shoe, comprising a plurality of .ring segments;a plurality of movable connecting devices mounted on each of saidsegments; a plurality of connecting springs united to and extendingbetween said segments; a plurality of cushion springs, one mounted oneach of said segments; a plurality of sliding connecting plates, onemounted on each of said segments; and a plurality of U-shaped flexiblegripper sections rigidly connected at their ends with pairs of saidconnecting plates.

In testimony whereof I have signed my name to this specication in thepresence of two subscrlbmg witnesses.

HERMAN STRONGSON.
